If you have something else than subsilver for instance, just mod that skin. The good thing with pphBB is that a skin error just looks ugly (a broken table or something weird), but you don't get parse errors. Just modify the code a bit till you are satisfied. I would not place the code all the time where supposed to, since I wanted the information created with the hack to display in another way. The best way to not have such problems is to not use another free skin, but mod the default one
